How can the strftime function be used to format dates in PHP?

To format dates in PHP using the strftime function, you can specify the format you want the date to be displayed in by using formatting codes. These codes represent different date and time components such as day, month, year, hour, minute, etc. You can then pass the date you want to format along with the desired format to the strftime function to generate the formatted date string.

$date = strtotime("2022-01-01");
$formatted_date = strftime("%A, %B %d, %Y", $date);
echo $formatted_date;
